Anna and Karen talk to you about where this is going.

Slumped together in the changing room, Karen and I simply couldn't stop kissing each other. It was another ten minutes before ether of us thought to get dressed. If she was angry about me cumming inside her, she showed no sign of it as she helped me back into my outfit and even quickly touched up my make-up. We left the changing room holding hands and giggling like school girls. Anna didn't have to ask what we had been up to; mostly because she had planned it, but also because she let slip that the two of us had been a bit loud.

My face was bright red. I was so embarrassed at the thought of people hearing me and Karen having sex in public despite the videos I had put up on my blog. This felt different; like I was flashing a big neon sign to the world that that I have a cock under my skirt in a women's clothes store. The blog posts felt disconnected and safer because I could see who was watching.

Both Karen and Anna saw the look on my face and gave me a kiss on cheek. Anna then leaned into my ear and whispered, "It's ok Selina. I don't think the clerk heard anything and even if she did, you sounded like a slutty girl in heat." My sisters words were making me feel horny again. I could feel myself starting to strain against my shorts.

We paid for my new clothes and spent the rest of the day like any group of girls going shopping together. Both Karen and Anna were staying close to me; our arms linked together with me in the middle as we went to different clothes stores and picked out more new outfits for me. I felt spoiled and even turned to my sister to say that she didn't have to go through all this for me. "Don't be silly," she said with smile. "I told when I found you out that I've always wanted a little sister to go shopping with. Besides, don't you want to have nice lingerie for when we do all that naughty stuff you wrote about on your blog?"

I froze, my face going red again. I forgot about the all the **** stuff I had posted; I had even mentioned that I had a real life sister I fantasized about.

"Hey, what about little old me?" said Karen who was listening in with a big sexy grin filling her dark features. "Girl him up all you want but he still has enough boy left that I want to have a second go at."

Before I had a chance to even react to that mind blowing declaration, Anna chimed in again, "Speaking of which; have you given any thought as to how far you are going to go with this?"

I looked at Anna with a puzzled look. I genuinely had no idea what she meant. Was she referring to our relationship? I was unsure. I was more then happy to let my sister lead me down the rabbit hole and only stopping were she decided. But something told me that wasn't it. I had to ask,"What do you mean?"

"Are you going to stop at crossdressing or are you going to take this further? You can't keep this from mom and dad forever and when they find out they will ask some really tough questions; assuming they don't just freak out of course."

You always did admire your sisters blunt way of putting things at times, except today. In all honesty it was something you never thought about. Even after all the sissy training videos and the sex toys, you still weren't sure what the end result of all this was going to be. You knew from other blogs and forums that some sissys did take the plunge into the world of gender reassignment; others just went with breast implants and a change in diet and exercise to give themselves a more feminine figure. But you also knew that many were happy just crossdressing and living as women. At the end of the day when all was said and done, you had to decide.

Was this just a kinky hobby or did you want to go further and how far would you go?
